With the development of manufacturing industries, the requirements of machinery and equipment is increasing. The need for precision and control of real-time elevates. At the same time, new requirements of the stability become more important. Traditional rotary screen printing system uses single chip processor synchronization, processing speed and accuracy is limited. And the interface control card use traditional finger connector, anti-shock capability and electromagnetic compatibility can not meet the current harsh industrial environments.For these deficiencies, the thesis proposes the design scheme based on CPCI bus, which has the same electrical characteristics with the PCI bus and good portability. The thesis outlines the status and trends of PC bus, focusing on an overview of the CPCI bus in Industry. The thesis makes a brief description of multi-axis synchronous control technique, especially rotary screen printing machine synchronization principle. Based on the original structure and the synchronization control system, the thesis proposes scheme based on CPCI interface. At last control scheme is demonstrated.The thesis analyzes selection basis of the core device in control system, and briefly describes the TMS320F2407 chip and EPM3128 chip. The thesis focuses on functions and principles and hardware structure of the main control board and servo control board. Then analyzes advantages of CPCI interface to the system, and discusses the CPCI interface circuit implementation. In addition, from the aspect of software implementation, the thesis describes main functions and key technologies of the main control board and servo control board. At last, some features make simulation and verification.In the end, the thesis makes design to optimize the system and a summary of the contents of this article,mainly is machine vision applications in the system.
